Major Malfunction: I met him when he was a thief on the streets. I took him in and taught him at my school.

Sunset Shimmer: What happened?

Major Malfunction: Like you Sunset, he wanted more. He aced all of his classes, combat most of all. But it wasn't enough for him. I tried to tell him what we want and what we need are two different things, but only drove him away. Seeing where it was going, I knew I would have no choice but to expel him. If only I had known then.

Sunset Shimmer: Why didn't you tell us anything about this before?

Major Malfunction: Because I buried the past and forgot all about him. I get nightmares about what happened.

Light Ultron: He got wind of it, didn't he?

Major Malfunction:(nods) When he found out, he was furious. In retaliation, he drove his melee weapon into the chest of one of his fellow students. They all fled. One of our janitors ran at him to avenge the student, but Flash Fire shot him multiple times.

Nighlock: What did you do boss?

Major Malfunction: I confronted him.

(flashback)

(we see Flash Fire(in Cybertronian form) on a cliff)

Major Malfuntion:(in flashback) It didn't have to be this Flash Fire.

Flash Fire:(in flashback) You're soft as you are weak.

Major Malfunction:(in flashback) You are making a mistake.

Flash Fire:(in flashback) Or am I?

Major Malfunction:(in flashback) You turned all of us against you.(unsheathes his swords and activates his Triple Bladed Sword and Cosmic sword) And now, I will do what I must.

Flash Fire:(in flashback)(takes out his own swords)

(Battle of the Heroes plays)

Major Malfunction: We fought for a long time before he made his escape. And that was the last time I saw him.

(we see them duel until Flash Fire escaped)

(flashback ends)

Major Malfunction: I trained him to do good. But he used that training to do evil.(to Human Fluttershy) So are you alright?
